The durability and strength of concrete in construction can be significantly compromised by permeability issues, which pose considerable challenges to its long-term effectiveness reliability. By analyzing six selected articles from the Scopus database, this study meticulously synthesizes findings on CAs improving these essential properties concrete. research documents analyzes key variables such as CA dosage, water–cement ratio, evaluation duration, treatment conditions, providing a thorough understanding factors that influence performance results robustly indicate reduce permeability, thereby enhancing resistance water other detrimental substances, simultaneously boosts compressive strength, leading stronger more durable structures. However, also reveals impact vary considerably depending specific conditions methodologies employed individual studies. This underscores importance standardized testing procedures ensure consistent comparable across different provides valuable insights for optimizing use formulations, ultimately aiming improve durability, performance, sustainability applications.

This study explores the effects of Polyurethane Foam (PUF) as fine aggregate and different NaOH molarity (M) to analyze rheological behavior, hardened properties microstructural behavior Geopolymer concrete (GPC) optimize replacement molarity. For this purpose, In PUF-GPC mix, GPC varied from 10 14 at intervals 2 with 1.5 % superplasticizers (SP) improve workability GPC. The optimum strength were attained 15% PUF 12 slump values, compressive, split tensile, flexural results. results indicate that optimal M, replacement, achieves highest compressive (40.4 MPa), tensile (5.15 (5.98 MPa) 28 days. These findings highlight potential PUF-based optimized a sustainable alternative in construction applications. concluded M concentration binder contents (fly ash-50% GGBS-50%) SP (2%) based provided better workability, behaviour.
